passt - Plug A Simple Socket Transport

	Commit message (Collapse)	Author	Age	Files	Lines
*	conf, pasta: Explicitly pass CLONE_{NEWUSER,NEWNET} to setns()	Stefano Brivio	2022-01-26	1	-2/+4
\| \| \| \| \| \| \|	Only allow the intended types of namespaces to be joined via setns() as a defensive measure. Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
*	passt: Drop <linux/ipv6.h> include, carry own ipv6hdr and opt_hdr definitions	Stefano Brivio	2022-01-26	1	-2/+0
\| \| \| \| \| \| \|	This is the only remaining Linux-specific include -- drop it to avoid clang-tidy warnings and to make code more portable. Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
*	passt: Add cppcheck target, test, and address resulting warnings	Stefano Brivio	2021-10-21	1	-4/+7
\| \| \| \| \| \| \|	...mostly false positives, but a number of very relevant ones too, in tcp_get_sndbuf(), tcp_conn_from_tap(), and siphash PREAMBLE(). Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
*	passt: Fix build with gcc 7, use std=c99, enable some more Clang checkers	Stefano Brivio	2021-10-21	1	-1/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	Unions and structs, you all have names now. Take the chance to enable bugprone-reserved-identifier, cert-dcl37-c, and cert-dcl51-cpp checkers in clang-tidy. Provide a ffsl() weak declaration using gcc built-in. Start reordering includes, but that's not enough for the llvm-include-order checker yet. Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
*	passt: Add clang-tidy Makefile target and test, take care of warnings	Stefano Brivio	2021-10-20	1	-1/+1
\| \| \| \| \| \| \|	Most are just about style and form, but a few were actually serious mistakes (NDP-related). Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
*	passt: Address gcc 11 warnings	Stefano Brivio	2021-10-20	1	-5/+10
\| \| \| \| \| \| \| \| \|	A mix of unchecked return values, a missing permission mask for open(2) with O_CREAT, and some false positives from -Wstringop-overflow and -Wmaybe-uninitialized. Reported-by: Martin Hauke <mardnh@gmx.de> Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
*	netlink, conf: Actually get prefix/mask length	Stefano Brivio	2021-10-19	1	-2/+7
\| \| \| \|	Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
*	pasta: Allow nanosleep(2) and clock_nanosleep(2) syscalls too	Stefano Brivio	2021-10-14	1	-1/+1
\| \| \| \| \| \|	...we need those to wait for terminating processes in the namespace. Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
*	netlink, pasta: Configure MTU of tap interface on --config-net	Stefano Brivio	2021-10-14	1	-3/+3
\| \| \| \|	Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
*	passt, pasta: Completely avoid dynamic memory allocation	Stefano Brivio	2021-10-14	1	-0/+253
	Replace libc functions that might dynamically allocate memory with own implementations or wrappers. Drop brk(2) from list of allowed syscalls in seccomp profile. Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
